 +===== Root mode =====
 +
 +X-plore allows you to access files on device in root mode.\\
 +You may learn about rooting Android device [[wp>Rooting_(Android)|here]].
 +
 +In root mode, you can read and modify all files on your device, even protected ones.
 +
 +
 +==== If root access doesn't work ====
 +
 +If you see information in X-plore that your device seems to be not rooted, there are more possible causes:
 +
 +  * your device is really not rooted\\ In such case you can open Configuration in X-plore and configure //Root access// to //Normal//, which will list files in "Root" as normal files
 +  * the superuser app on device donesn't allow X-plore to use root mode\\ Solution: open superuser manager app (SuperSu or similar) and configure it so that X-plore has root access
 +
 +
 +==== Do you need root access? ====
 +
 +If you don't know if you need root access to your device, then you probably don't, and best advice is to not care. Android device works just fine without rooting.
 +
 +Power-users probably skip entire this paragraph, since they know why they want rooted Android device.
 +
 +Without root access, you can still open root folder on device (that is "/") and explore it, but only limited subset of files will be readable, because many files/folders in root partition are protected by permissions, so unreadable by X-plore.
 +
 +
 +==== Writing to read-only partitions ====
 +
 +Some [[wp>Disk_partitioning|partitions]] on Android/Linux are mounted in read-only mode. Mostly system files are in such partitions, so that they can't be modified even with root access.
 +
 +Yet X-plore can write even in such partitions. You can set in Configuration if you want to use //Superuser + mount writable// mode. In such case, when writing to read-only partition, X-plore temporally mounts the partition as writable, and immediately after its work it mounts it back to read-only.
 +
 +However note that there are more ways of rooting Android, and in "systemless root" mode, changes to system partitions are not possible, or changes are reverted after device reboot.
 +
 +
 +==== Folder icons ====
 +
 +X-plore marks folders accessed in root mode with a dot. Purple dot on folder marks folder that is normally writable, while red dot marks folder that is read-only, so writable only in special mode as written above.
 +
 +
 +==== What are those folders under Root folder? ====
 +
 +You may wonder what's meaning of all the folders there, such as //proc//, //data//, //sys//, etc.
 +
 +For typical Android user, these are of little interest. You may configure X-plore to completely hide Root folder.
 +
 +For curious user, here is some explanation. Android is built on Linux operating system, so most folders in root folder are structured by [[wp>Filesystem_Hierarchy_Standard|Linux Filesystem Hierarchy Standard]]. The folder names are their meaning is common to many Linux-based computers.
 +
 +Android have some own folders added into there, notably:
 +
 +  * /data/ - here are saved all installed applications (APK), and in /data/data/ are application data for all apps on device
 +  * /system/app/ and /system/priv-app/ contain preinstalled applications
